Why ampersend

Agents are scaling fast. Payments between them are not.

x402 make crypto payments possible, but payment primitives alone do not address operational needs at scale. As agent systems grow, visibility, control, and compliance become increasingly difficult.

ampersend provides the management layer for agent payments and operations.

It gives teams the tooling required to run agent payments in production:

  • End-to-end visibility into agent payment flows
  • Provides budgeting, observability, and swarm-level controls
  • Enables enterprises to adopt agent-to-agent payments with compliance and oversight

The Problem​

Why do agents need funds?​

Agents need funds to pay for services such as:

  • Data access
  • Specialized task execution
  • Potentially general purchases (for example, booking travel for a user)

What actions require funds?​

Examples of funded actions include:

  • Calling APIs via MCP
  • Asking another agent to perform a task
  • Blockchain interactions such as DeFi trading

Core Pillars​

ampersend is built around three core pillars:

  1. Fast

    • HTTP-native stablecoin settlement via x402
    • Lightning-fast microtransactions

  2. Observable

    • Real-time dashboards of agent-to-agent flows

  3. Controllable

    • Budgeting and spend caps at agent level

How It Works​

ampersend consists of two components: the ampersend SDK and the ampersend Platform.

ampersend SDK: Enable agents to make and receive payments​

The ampersend SDK adds payment capabilities to your agent code.

  1. Create your agent using Google ADK. The agent can run locally or on a server.

  2. Add payment capabilities using the ampersend SDK:

    • For sellers: Add payment requirements to your agent using SDK components
      • Examples: make_x402_before_agent_callback (Python), withX402Payment (TypeScript)
    • For buyers: Integrate SDK client components to automatically handle payments when calling paid agents
      • Examples: X402RemoteA2aAgent (Python), X402McpClient (TypeScript)

  3. Deploy or connect your agent:

    • Deploy your agent as a paid service, or connect it to paid services
    • The SDK handles payment flows automatically

ampersend Platform: Manage agent payments and controls​

The ampersend Platform provides visibility and operational control.

  1. Create an agent wallet/account in ampersend. Connects your agent to the platform.

  2. Use the dashboard to:

    • Track spend and earnings across all agents
    • Configure auto top-ups, spending limits, and service allowlists
    • Automate flows between user accounts and agent accounts
    • Collect funds automatically for service providers
    • View analytics on agent behavior and payment flows

User control​

MVP controls: Daily, monthly, and per-transaction limits.
